To simplify <span>2x + 8 = -6, the easiest way is to manipulate the equation one step at a time:

</span>2x + 8 = <span>-6
</span>2x = <span>-14             (subtract 8 from both sides)
</span>x = -7                 (divide both sides by 2)

Minor Arc AC =  110 degrees  (given)
As indicated in the hints,
OA=OC  => OAC=OCA=(180-110)/2 = 35
Similarly,
OAB=OBA=(48-35)=13
=>
OBC=OCB=(180-35-35-13-13)/2=(180-96)/2=84/2=42
=>
Angle B = 13+42 = 55 degrees

Check:
55+55+35+35+13+13 = 180 degrees (angles of a triangle)  ok.

The Recreation Center has an L-shaped pool. One pool is 8 meters by 6 meters. The other part is 12 meters by 6 meters. The whole
defon

Answer:

480m³

Step-by-step explanation:

The entire pool have the same depth which is 4metres

Since the pool is L shaped, we will find the volume of each part and add them together to get the volume of the entire pool.

Using the formula for calculating volume of a rectangular box

V = lwh

L is the length

w is the width

h is he height

For the first pool.

Length = 8m

Width = 6m

Height = 4m (depth)

Volume = 8×6×4

Volume = 192m³

For the other pool.

Length = 12m

Width = 6m

Height = 4m (depth)

Volume = 12×6×4

Volume = 288m³

Volume of the entire pool = 192+288 = 480m³

It means:

9\cdot9\cdot9\cdot9\cdot9\cdot26\cdot9\cdot9\cdot9=1,119,214,746

There are 1,119,214,746 possible reservation numbers.

(7+3i)-(3-9i)complex numbers
DanielleElmas [232]

Answer:

C

Step-by-step explanation:

For this, you want to treat i like any other variable, and combine like terms. However you need to keep in mind that there is a negative sign before the second set of parentheses. This means everything inside it should have a negative before it. So we can write it like this:

(7 + 3i) - (3 - 9i)

7 + 3i -3 +9i

4 + 12i

Hope that helps!
